Photoinduced energy transfer and electron transfer processes have been found between the excited singlet state of Zn-porphyrin and C60via an oligothienylenevinylene bridge depending on the length of the oligothiophene and solvent polarity.

diferrocenyl cations, the transition from a charge delocalized to a localized state is addressed by resonance Raman spectroscopy and supported by theoretical model chemistry. The shorter members, dimer and tetramer, display conjugated structures near the cyanine limit of bond length equalization as a result of the strong interferrocene charge resonance, producing a full charge delocalized mixedvalence system
